Air conditioning and temperature control are nowadays considered basic equipment for home comfort. Although it may seem a simple system, air conditioning is actually a much more complicated system than we think. Moreover, it is becoming more complex every day (active filters, dual-zone air conditioning, etc.).
During the winter, we tend to forget about it until the heat arrives and we turn it on again. Precisely at that moment, it is susceptible to signs of fatigue, which leads us to recharge it, inspect it or simply verify that it is working properly. Before working on the air conditioner or replacing the refrigerant, it is necessary to replace the old refrigerant with a new one.
In this circumstance, we speak of bleeding the air conditioner. After reading this article, you will be able to understand how to remove the air conditioner from your vehicle at your residence.
How to Remove Refrigerant From Car AC
You will need air conditioning recovery equipment in order to properly remove Freon at home. The refrigerant material recovered and recycled by the A/C recovery equipment can be recovered and recycled from the vehicle. When this equipment has completed the recycling and removal of the refrigerant, it is considered complete.
Step 1: Locate the Low-Pressure Service Port.
The low-pressure inlet port is usually located between the compressor and evaporator, as shown in the diagram. The low-pressure side often referred to as the low-pressure service port, is protected by a black or blue plastic box.
Next, go to the evaporator following the routing. Under the dashboard, near the firewall and windshield, is a small evaporator for cooling purposes. The low-pressure service port is protected by a black or blue plastic plug, which must be replaced each time the pressure drops.
Step 2: Start The Recovery Machine
Locate the low-pressure service port and connect the recovery equipment to it using the appropriate connector.
To remove Freon vapor and non-condensable gas from the system, operate the recovery equipment. Some refrigeration fluids, on the other hand, will remain in a liquid state. The machine’s pressure system will then direct the liquid to the vaporization chamber.
Step 3: Disconnect the Recovery Machine
Connecting the Freon to the vehicle air conditioner service port is the last step in removing Freon from the vehicle air conditioner.
Before removing the recovery machine from the server, make sure the server hose valve is closed.
How Often Does an AC System Need to Get Recharged?
It is not essential to recharge the air conditioning system every summer, nor is it necessary to recharge the system every year. In a new vehicle, it is only necessary to perform this service every two years after a complete cleaning of the system. Although this is true every summer, many motorists who notice that their car’s air conditioning is not working properly, i.e. it does not cool or cool the passenger compartment as it should, look to garages that offer air conditioning recharges without the need for further inspection or testing.
It is possible that the air conditioning in our car does not have the necessary cooling capacity to keep us cool as it did last summer for one of these three reasons:
1. The cabin filter has become clogged or fouled.
There are many types of breakdowns, but this is the least serious and least expensive. It is because the filter is so clogged that cold air cannot reach the passenger compartment. It is therefore essential to perform regular maintenance throughout the year. If the filter is very old, it may need to be cleaned or replaced.
2. There is an electrical problem.
A relay, fuse, or connection somewhere needs to be replaced.
3. There is a gas leak in the system.
The air conditioning circuit is a closed circuit, and although some refrigerant gas leaks may occur as a result of the system itself, these leaks are small and should not be evident when driving the vehicle in question. When it is necessary to recharge the air conditioning gas, it is most likely because there is a leak in the system. In addition, there is a more serious problem that will be determined by the location of the leak (pipe, condenser, evaporator).
How Much Does It Cost To Recharge Your Car’S Ac?
In most cases, the cost of a professional air conditioner recharge ranges from $150 to $300, depending on the make and model of your car. Due to the gradual loss of refrigerant that occurs over time, this repair should be included in your vehicle’s regular maintenance schedule. It is suggested that this service be performed on a vehicle approximately every 100,000 miles, depending on mileage.
Removing Freon from your car at home is not as difficult as you think. If you follow these steps, you can easily remove Freon from your car’s air conditioner.
The maintenance of the air conditioning, like that of any car in general, is not cheap, but not doing it can be even more expensive. The basic maintenance consists of annual cleaning of the air conditioning circuit accompanied by an anti-bacterial treatment. Every two years, in addition to cleaning the circuit, the filters are replaced and the refrigerant gas is recharged.
